ESB Zusatz.
Zur Verminderung der Anfälligkeit von
KW-Telefonieverbindungen nach Übersee hatte die Reichspost
bereits 1931 auf Vorschlag der Fa. Telefunken (Dr. W. Runge)
einen ESB-Verkehr Berlin-New York eingerichtet. ....und der
Zusatz EB1/3a "Käthe" von Siemens zu Fu.H.E.c
(1944/45) wurden übrigens auch gelegentlich für Abhörzwecke
eingesetzt. Fritz Trenkle: Die dt. Funkpeil- und
-Horch-Verfahren bis 1945, S.35.

All front marking are removed sometime in the 50's, but
Hans Jürgen Keller / DH1AB has sent me most of them, and he
mentions that it is possible to get more such things from
Günther Hütter <g.huetter@t-online.de>.
